We had a 6.5 SP7 server failure (dirve array failed). We re-installed Netware 6.5 SP7 (which by default installs edir SMP). We then installed edir 8.8 sp2 by mistake - all other servers (120) are running because we still have a few Netware 6.0 sp5 servers that do not support 8.8. We would prefer to downgrade this one server edir to
Is there a way to do this without reloading Netware?

What is the impact if we leave as is?

There are two read/write replicas in that partition - one running and the other running 8.8 sp2.
